Plasma display panel and manufacturing method thereof

Abstract

An exemplary plasma display panel according to one embodiment includes a first substrate and a second substrate, a barrier rib, address electrodes, a phosphor layer, display electrodes, and a first dielectric layer. The first and second substrates are disposed facing each other. The barrier rib is disposed between the first and second substrates and forms discharge cells. The address electrode is formed in one direction on the first substrate corresponding to the discharge cells. The phosphor layer is formed in each discharge cell. A display electrode is formed in a direction that crosses the address electrode on the second substrate. A first dielectric layer covers the address electrode. The first dielectric layer is formed, in the direction of the length of the address electrode, up to at least one of the edges of the first substrate.

PDP has excellent benefits in multiple display characteristics, such as brightness, contrast, after-image, and viewing angle, over other display device types. A PDP is formed by combining a front plate and a rear plate together. The front plate is c...

AI Technical Summary

Benefits of technology

The present invention provides a manufacturing method for a plasma display panel with a uniform thickness of the substrate and a plasma display panel made using this method. The method involves forming address electrodes and a dielectric layer on one substrate, and then combining it with another substrate with display electrodes and a dielectric layer. The resulting panel has a consistent thickness across the entire panel. The dielectric layer is formed using a dielectric material paste that is continuously applied to the substrate and then cured. The thickness of the dielectric layer may vary in different portions of the substrate. The technical effect of the invention is to provide a plasma display panel with improved uniformity in thickness and a manufacturing method for its fabrication.

Problems solved by technology

Consequently, it is difficult to form a dielectric layer having a uniform thickness on the substrate.

Furthermore, such a problem becomes much more serious when a plurality of substrates are fabricated using one mother glass.

That is, because spraying of dielectric material paste is stopped at a region between neighboring substrates, it is difficult to form a dielectric layer with a uniform thickness over the whole substrate.
